ARMADILLIDIID^. 



III. — Genus ARMADILLWIUM Brandt 



Four species of ArmacUllidium {vulgare Latr., pictum Brandt, 

 pulehellum Zencker and sulcatum M.-Edw.), are known froni 

 Belgium Ihe last two of which hâve not yet occurred in Britain. 

 A fifth species, A. nasatum B.-Lund, is recorded below. 



1. — Armadillidium nasatum Budde-Lund. 



ArmacUllidium nasation Budde-Lund, Cj'ustacea Isopoda Terrestria, p. 51, 

 1885; DoLLFUs, Le Genre Armadillidium, p. 10, fig. 12, 1892; Stebbing, 

 AN^f. and Mag. of Natural History, ser. 6, XV, p. 22, 1895; Norman, Ann. 

 AND Mag. of Natural History, ser. 7, IIl, p. 57, pi. VI, figs. 5-8, 1899, 



A species recorded from France, Spain, Italy and the Soulh West 

 of England. Early Ihis year (1907) Mr. Patience discovered that 

 A. nasatum lived commonly in green-houses at Glasgow, etc., 

 where, Ihrough his kindness I had llie pleasure of first seeing the 

 species. I hâve since found it in varions British Ipcalities and in 

 Belgium. 



Belgium. — Several spécimens in hol-houses at Brussels and Ant- 

 werp, November 1907. 



The following Land- Isopoda were aiso noted : Trichoniscus pusU- 

 lus Brandt, Oniscus asellus L., Philoscia muscorum Scop., Por- 

 celiio scaber Latr., P. pic tus Brandt and Batzeburg (one spéci- 

 men, Antwerp), P. dilatatus Brandt i a few at Antwerp and in extra- 

 ordinary profusion at Brussels), Metoponorthus pruinosus Brandt. 

 and Cylisticus convexus Hartmann. 



Had time permitted we should undoubtedly hâve laken otlier and 

 more interesling forms, but il must be remembered that the above 

 records are the results of a liltle more that two hours collecting and 

 that a good portion of this time was devoted to the Thysanoptera. 

 I should be very glad to hâve the opporlunily of examining any 

 woodlice from Belgian gardens and hot-houses, especially Ihe smaller 

 species, the Trichoniscidœ .
